B,Movement
Explanation:
Your musculoskeletal system includes bones, muscles, tendons, ligaments and soft tissues. They work together to support your body's weight and help you move. Injuries, disease and aging can cause pain, stiffness and other problems with movement and function.
Answer:
The product would have more acidity than Diethyl malonate
Explanation:
For this question, first, we have to start with the structure of the bromination reaction. <u>The bromination would add a "Br" atom</u> in the middle carbon between the ester groups. Therefore, the molecule produced would be <u>diethyl 2-bromomalonate</u> and the formula of this compound fits with the reported by the question:
Now, if we have to analyze the acidity we have to check the <u>most acidic hydrogen</u>. In this case, is the "H" in the middle carbon (red hydrogen). In the Diethyl malonate, we have an <u>inductive effect</u> caused by the carbonyl groups on each side of the middle carbon. In the diethyl 2-bromomalonate, we have this same inductive effect plus the Br atom bonded to the same carbon. Therefore, would be <u>easier to remove the hydrogen</u>. So, diethyl 2-bromomalonate would ba more acidity than Diethyl malonate.
See figure 1

Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced molecular equation for the reaction of aqueous sodium sulfate, and aqueous barium nitrate is :
